6 Button Mode

This cheat makes it possible to play the game with a new 6 Button controller scheme. You need a 6 button controller plugged into port 1 and any regular controller in port 2.
Highlight "Options" on the main menu. Normally when you're in the Options menu, it says "Options" at the top, with an S on the end.
Highlight Options but don't go into it yet. On Controller 1, hold the Mode button and on Controller 2, hold UP on the D-Pad and the C Button. With all these buttons held down, press Start on controller 1.
Now you're in the Options menu, it now just says "Option" at the top without an S. This means 6 Button mode is on. This is what each button does.
A is the Block button.
B is a Melee attack.
C is Jump
X uses Ninjitsu magic
Y and Z throw Shurikens
This allows you to use Melee move at any time rather than at close range or when out of Shurikens.
Enjoy!
